摘要
采用厌氧／好氧生物脱氨－絮凝法处理焦化废水，出水中ＮＨ＿３－Ｎ＜１５ｍｇ／Ｌ，ＣＯＤ为９６－１５８ｍｇ／Ｌ。利用甲醇残液及其他有机废水作为外加碳源，可以达到以废治废的目的。
Coking-plant wastewater can be treated by anaerobic/aerobic(A/O)process fOrbiological removal of nitrogen,followed by flocculation process with polymerized ferricsulfate as flocculant,resulting in NH_3-N<15mg/L and COD: 96-158mg/L in the effluent.Methanol residue or other organic wastewater can be used as supplemental carbon sourcesfor denitrification process.
